T 0 all to 710m it may concern Be it known that l, HENRY E. MAURER, J12,citizen of the United States, residing at Springfield, in the county ofSangamon and State of Illinois, have invented a certain new and usefulImprovement in Liquid-Dis:- pensing Apparatus, of which the following isa full, clear, concise, and exact description.

My invention relates to liquid dispensing apparatus and has a number ofobjects and advantages in view.

In my Patent 1,308,091, dated July 1, 1919, I have illustrated a singleliquid container and mechanism for filling and emptying the same, thefilling apparatus being idle while the contents of the container arebeing discharged. The equipment disclosed in said patent is'primarily ofutility in supplying gasolene to the filling tanks of automobiles.

It is the general object of my present in vention to provide anapparatus employing two containers preferably, though not necessarily,having a single discharge hose and provided with mechanism wherebyliquid may be entered into either container while being discharged fromthe other so that there will be no delay in dispensing the liquid whichwas hitherto experienced when the apparatus employed but a singlecontainer.

In the preferred embodiment of the in vention, when it is employed inthe construction of gasolene dispensing apparatus, each container is inthe form of a five gallon capacity inverted glass bottle, the aggregatecontents of which would at no time be in excess of five gallons, thelimit usually pre scribed by fire underwriter associations.

The equipment of my invention will enable all or any part of thecontents of either bottle to be withdrawn while a similar quantity isbeing entered into the other bottle so that all or any portion of thecontents ofi either bottle may be withdrawn while a correspondingquant-ity is being entered into the other bottle to make the aggregatequan tity of liquid in both bottles similar to the quantity contained ineither bottle when filled.

In the apparatus of my invention liquid is introduced into the bottlesor other containers consequent upon the exhaustion of air from suchcontainers and in order that no'liquid may be entered into either container while a corresponding quantity of liquid is not being withdrawnfrom the other Specification of Letters Patent.

container, I employ means individual to each container for preventing orpermitting exhaustion of air therefrom and controlled by the liquiddischarge enabling means individual to the other container to permit airexhaustion upon liquid discharge and to prevent air exhaustion whenliquid discharge is prevented.

I will explain my invention more fully by reference to the accompanyingdrawings showing the preferred embodiment thereof and in which Fig. 1 isa diagrammatic View illustrating the apparatus of my invention incertain adjustment; Figs. 2, 3 and t are diagrammatic views illustratingother adjustments of a part of the apparatus, the views of the valvingmechanism being respectively taken on line A-A, BB, and C@ of Fig. 5excepting that the angular adjustment of the valving mechanism differsin the different figures; Fig. 5 is a plan View of the valvingmechanism; Fig. 6 is a sectional view on line 66 of Fig. 5; Fig. 7 is aside view of the valving mechanism shown in Fig. 1; and Fig. 8 is detailview illustrating another part of the valving structure.

Like parts are indicated by similar characters of reference throughoutthe different figures.

Each container 1, 1' is desirably in the form of an inverted glassbottle. As I have practiced my invention each bottle is of five galloncapacity. Flach bottle neck 3 is received in an annular or tubular seat4 whose bore is in direct communication with the bore of the bottle neckto afford direct passage for liquid through the bottom of each container(the bottle neck) not only outwardly in the dispensation of the liquidfrom the container, but also inwardly to replenish the supply of liquidwithin the container.

The gasolene or other liquid is supplied to the containers from a supplytank 5 which is ventec, as at 6. The liquid flows from the tank to thecontainers through the piping 7 and flows from each container throughthe eduction nipple 9 and the discharge hose 9 connected with thenipples of both containers. Each container may be drained or emptiedback into the tank through the bypass 10 that connects the passage 3with the pipe 7, it being desirable to do this when the apparatus is outor service, as at night.

A suction-vent tube 11 is preferably within and extends to the top ofeach containe When liquid is being discharged from either container, thecorresponding tube is thrown into communication with the external air toact as a vent. When liquid is being passed into either container, thistube thereoi is thrown into communication with the air exhaust pump 12or the vacuum tank in which vacuum is maintained. by said pump.

Each container has a valve lei.- individual thereto which serves,according to its adjustment, to seal tie inlet-outlet end 3 of thecorresponding container, or to establish conz A nection between suchcontainer and the discharge hose and then to cutoil comnuinica- .tionbetween the supply b i k and such container, or to establish connectionbet ecen such container and the supply tank and then to cut oilcommunication between such coutainer and the discharge hose. Eachcontainer has a valve 153 individual thereto which, according to itsadjustment, es ablishes or breaks the continuity of a co" spendingby-pass 16. An air valve 16 is individual to each container but is mace11 one unitary structure with the aforesaid valves individual to theother container this valve being operated, when liquid is caused to flowfrom one container, to permit of the Xhaustion of air from the othercontainer and allow the introduction 01 just much liquid into the lattercontainer as is being dischaured from the first container. Each valve16, according to its adjustment. establishes or breaks connectionbetween the cor responding vent tube 11 and the external air; orestablishes and breal-ts connection between said vent tube and thovacuui'n tank. The valves 14- and 1:") pertaining to each container andthe valve 16 individual to the other container are formed in a unitarystructure, as shown in Figs. 5-, 6 and 7, such unitary structure beingpreferably a single piece of brass 17 suitably ported to have it- :Eormall of the valves, the composite valve 17 operating in a single valvecasing 18, that is ported correspondingly to said valve. Each compositevalve and its casing are tapered, a spring 19 servingto hold the valvein snug engagement with its casing to avoid leakage. Each 01 the valvesis provided with a handle 20 having a spring pressed plunger detent 21for holding the handle and valve in the position to which it isadjusted. Each handle sweeps over a dial 22 having notches beingpositioned at the dif ierent places to which each composite valve is tobe adjusted to secure the desired control and association of thecorresponding container inlet-outlet 3. ln 1 the right hand valve handleis shown at the notch marked Hose establishing valve adjustment thatlimits the right hand container 1 to connection wlth the 'dellvery hose9 and the external air. When each valve handle is placed at the notchmarked To hold the valve adjustment shown in Fig. 2 is secured. By thisadjustment the corresponding container is shut off from communicationwith the hose and the supply tank. When the bottle is to be filled thevalve handle is placed at the notch marked To fill bottle (Fig. 3) andthe left hand valve of Fig. 1 0 bring the corresponding container openng3 into communication with the supply tank 5 and the upper end of thiscontainer into communication with the vacuum tank 13 by way of the tube11 to exhaust air from the upper end of the bottle to occasion flow althe gasolene or other liquid upwardly into said container from thesupply tank ll hen a bottle is to be drained the corresponding tube 11is thrown into communication with the external air and the continuity oithe by pass 10 is established, whereupon all oi? the liquid remaining insuch container is discharged through'the pipe '2 back into the tank 5.

The tube 11 of each bottle is connected with a valve chamber 24. A float25 is located within each valve chamber and carries a valve 26 "forengagement with a seat 27 when connection with the vacuum tank 13 is tobe cut oil, each valve 26 being separated iiiTOlIl its seat whencommunication between the corresponding container and the vacuum tank isto be established. When a container is about filled a small portion ofthe liquid will flow downwardly through the tube 11 into the valvechamber 24 and when received in suliicient quantity within this chamberthe float will rise to engage the valve 26 with its seat 27 wherebycommunication between the vacuum tank and the container is automaticallycut oli to cause the cessation of upward flow of liquid from tank 5 intothe container. The small portion of liquid remaining in the valvechamber 24 and the corresponding tube 11 at the conclusion of eachfilling operation is sufiiciently sucked back into the correspondingcontainer to lower the that as the liquid comes to itsfnormal upperlevel, whereby the valve 26 is automatically opened to permit the valve16 to.

function.

Fig. 1 well illustrates the valving mechanism of the entire equipmentand clearly shows the manner in which the inflow of liquid to eithercontainer is absolutely prevented unless the corresponding quantity ofliquid. is being discharged from the other container. l hile l haveherein shown and particularly described the preferred embodiment of myinvention, 1 do not wish to be limited to the precise detailsofconstruction shown as changes may readily be made without departingfrom the spirit of my invention, but having thus described my inventionit claim as new and desire to secure by Letters Patent the following 1.Apparatus for dispensing liquid .in, cluding two liquid containers;eduction piping communicating with said containers and through whichliquid may be discharged therefrom; a source of liquid; induction pipingconnecting said source of liquid with said containers and through whichinduction piping liquid may be supplied to the containers from saidsource; vent tubes communicating with the upper portions of thecontainers; an air pump; and valving means adjustable to connect thevent tube of either container with the external air and the eductionpiping with such container to discharge liquid therefrom and to cut offthe induction piping from such container and at the same time to cutofi' the eduction piping from the other container and to connect thevent tube thereof with the air pump and to connect the induction pipingtherewith to fill such other container.
